Abstract (en)
[origin: EP3680798A1] This application provides a process monitoring method and an apparatus. The method includes: determining, by a processing unit, a first mapping relationship and a second mapping relationship, where the first mapping relationship indicates that an access rule of a first physical address is access forbidden, and the second mapping relationship indicates that an access rule of the first physical address is access allowed; determining, by the processing unit, that a target mapping relationship is the first mapping relationship; sending, by the processing unit, a first access request to a memory control unit; receiving, by the processing unit, first exception information sent by the memory control unit, where the first exception information is sent when the memory control unit determines that the access rule of the first physical address in the target mapping relationship is access forbidden; monitoring, by the processing unit, a process based on the first exception information, and switching the target mapping relationship; and re-sending, by the processing unit, the first access request to the memory control unit. Therefore, monitoring of the process can be easily implemented.
